The Air Gap (AG) range of Eddy Current Dynamometers has been designed to be compact, robust and to allow easy maintenance. The narrow yet durable design, small footprint, and the exclusive material and construction technique ensures many years of service. These units are bi-directional, fitted with 40,000-hour bearings and extremely accurate (0.25% Full Scale Torque).
Each eddy current dynamometer is fitted with oil injected half couplings at either end of a non-magnetic stainless steel shaft which is supported in grease lubricated, deep groove ball bearings. The non-magnetic shaft means negligible magnetic field dispersion. The dynamometer casing houses twin magnetizing coils that produce a retarding controllable magnetic field that resists the applied torque. Heat generated in this process is dissipated by cooling water
